SMNR4020-2.2UH是国产品牌顺翔诺(SXN) 推出的一款小型化表面贴装(SMD)功率电感,型号命名规则清晰:“SMNR”代表系列定位,“4020”对应封装尺寸(4.0mm×4.0mm×2.0mm),“2.2UH”明确核心电感值。作为中低功率电源管理场景的通用型产品,其设计兼顾了小型化、电流承载能力与成本控制,适配多数便携及嵌入式设备的供电需求。
功率电感的性能核心取决于电气参数,SMNR4020-2.2UH的关键参数具备明确的实用价值:
SMNR4020-2.2UH采用4×4×2mm SMD封装,具有以下物理特性优势:
结合参数与封装特性,SMNR4020-2.2UH的典型应用场景包括:
SMNR4020-2.2UH在同类产品中具备明显的性价比优势:
若实际电流需求略高于3.4A,可考虑同系列更高电流型号;若电感精度要求高于±20%,需结合电路增加补偿电路。但对于多数中低功率电源管理场景,SMNR4020-2.2UH已能平衡性能与成本需求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
